The graphics card market it a somewhat fickle creature. At times, cards which should be amazingly popular fail to attract attention while some underperforming products end up being best sellers. We’re not yet sure which category the GTX 460 will eventually fit into but if the initial buzz about it translates into actual sales, NVIDIA will have a winner on their hands from every perspective.

Available in both 768MB and 1GB formats, the NVIDIA GeForce GTX 460 represents a giant leap forward for the Fermi architecture. At the heart of these two cards beats the GF104 core which effectively moves away from the power-hogging and expensive GF100 in order to offer a much more appealing option to the mid-range market. As our original review showed, both cards offer an incredible price / performance ratio that simply beggars the competition at the most widely used resolutions. The GTX 460 has also shown itself to be highly overclockable which could finally lead to some pre-overclocked versions that sport real-world performance increases.

Due to its length, we weren’t able to include SLI testing in the original review and considering two 768MB GTX 460 cards retail for $100 less than a single GTX 480, dual mainstream Fermi cards could be a great solution for increased performance. To make matters even better, we saw in our GTX 470 SLI review that NVIDIA has shown their new architecture to have some downright jaw-dropping multi card scaling. If the GF104 can repeat that feat, we may have something special on our hands.

EVGA was gracious enough to send along a pair of their GTX 460 768MB Superclocked cards which retail for $220 apiece. With it they offer all of the usual benefits EVGA is known for (we’ll get into them a bit later) as well as the pre-overclocked goodness of their Superclocked versions. However, there is one thing we should mention: EVGA has started selling two versions of their GTX 460 cards: one with and one without a lifetime warranty. Pay special attention to the product number of the card you are buying since any with AR are graced with a Lifetime Warranty while the slightly less expensive –TR branded units have a 2-year warranty.

This review will serve as three reviews in one since we will be looking at the performance of two GTX 460s in SLI along with both single and dual card results for EVGA’s GTX 460 768MB Superclocked Edition. It should be interesting, that’s for sure.

Say Hello to the GF104

Say Hello to the GF104


When it came to shrinking the GF100 which graces the GTX 480, GTX 470 and GTX 465, NVIDIA looked closer at the architecture and decided to make a few changes to a number of areas. In order to scale back things, certain sacrifices would have to be made if the original GF100 layout was kept as we speculated in our original article. The main issue with the GF100 is a real lack of texture units as you start eliminating Streaming Multiprocessors. So, if linear scaling was kept, NVIDIA have had possible lower-end GPUs with 320 cores or fewer cores but only 40 or fewer texture units. Like it or not texture performance is still one of the cornerstones of modern games and if that trend had continued, NVIDIA may have found it very hard to compete with the HD 5000 series.

One of the primary reasons behind designing the GF104 was the need to lower the thermal and power consumption needs of the Fermi architecture by producing a more compact core. Not only is this easier and less expensive to produce but it also allows NVIDIA to attack certain price points which ATI may have left vacant.

GTX-460-20.jpg
GTX-460-21.jpg

The differences between the GF100 and GF104 layouts start with the Streaming Multiprocessor which houses the CUDA cores, Texture Units, Polymorph Engine, Warp Schedulers, Load / Store units, SFUs and their associated cache hierarchies. Let’s start at the top and make our way down.

Instead of two Dispatch Units each being accessed by their own Warp Schedulers, the GF104 makes use of a 2:1 ratio between the dispatch units and the schedulers while the number of Special Function Units has doubled per SM. As a result, transcendental instruction performance has been increased over the GF100 even though the number of concurrent threads has remained as it was. Otherwise, the Instruction Cache and the Register File size stay the same as GF100.

The main changes to the SM come with the number of CUDA cores as well as the number of texture units each houses. Instead of the usual 32 cores per SM, the GF104 uses a structure which allows for 48 cores along with 16 load / store units and 8 Special Function Units. This in and of itself is quite an eye opener but the real differences are with the number of texture units each Streaming Multiprocessor houses. The GF100 cards have four texture units per SM while the NVIDIA equipped the GF104 with eight TMUs per SM. This can and will lead to a massive increase in texture performance which will benefit older DX10 and DX9 games.

GTX-460-17.jpg

Much like the GF100 layout, the GF104 makes use of four Streaming Multiprocessors (SMs) and their associated Polymorph Engines per GPC along with a common Raster Engine. The only differences are the ones we mentioned above and the result is a GPC with sufficiently more horsepower than the GF100 was able to put forth.

GTX-460-16.jpg

Above is a picture of a full GF104 core and we’re hoping you are paying very close attention to its layout and the number of cores it houses within its two GPCs. In total, there are 384 cores, 64 texture units, 32 ROPs, 512KB of L2 cache and four 64-bit memory controllers. It is quite evident that even though the GF104’s SM structure got a face lift, NVIDIA kept the ROP, L2 cache and memory controller array as is when making the transition from the GF100.

To us it looks like NVIDIA took some of the lessons it learned from the GF100 and put them towards designing a core that is infinitely more adaptable for the sub-$250 market. Not only is the GF104 much more compact than the higher-end silicon (it has 1.95 billion transistors versus the GF100’s 3 billion) but it is supposedly quite a bit more efficient as well. The one thing which could hold it back is the fact that it only has a maximum of eight PolyMorph Engines that are essential for DX11 performance. For example, if you wanted to achieve 384 cores with a GF100, a total of 12 SMs (and 12 PolyMorph Engines) would be needed. Will these eight or fewer engines have a negative impact on the GF104’s DX11 performance in future applications? Only time will tell but for the time being this looks like the perfect graphics processor for the current mid-range market.

The GTX 460: GF104 Slimmed Down

The GTX 460: GF104 Slimmed Down


GTX-460-68.jpg

According to NVIDIA, the GTX 460 is meant to compete with ATI’s HD 5830 from a number of different aspects. We have always maintained that ATI’s lineup is a bit weak between the $170 and $250 price brackets and this is exactly where we see this new card hitting. Before we go on, it should also be mentioned that the GTX 460 is compatible with 3D Vision Surround and NVIDIA Surround as well.

The GTX 460 is being offered in two different flavours that are distinguished from one another by their price and memory size: 1GB and 768MB. At face value, the distinguishing qualities between these two cards may be minor but since the L2 cache, ROPs and memory controllers scale in a parallel fashion with one another, the elimination of 256MB of memory causes a bit of a domino effect. So the 768MB card not only ends up with less memory than its bigger brother but also less ROPs, 384KB instead of 512KB of cache and significantly narrower bandwidth as well. Clock speeds, core / texture count and other aspects stay constant between the two cards. What’s even more impressive is the number of texture units equals those on a GTX 470 while TDP (not to be confused with actual power consumption) is actually quite low for a 400-series card but remember that ATI’s figure of 171W for the HD 5830 is based on max board power.

GTX-460-23.jpg

When you look closely at NVIDIA’s lineup, everything looks extremely well defined until you throw the GTX 460 into the mix. The main “problem” we see is the GTX 460 stepping on the toes of the $270 GTX 465 and could make the more expensive card look like a lame duck in terms of pricing, efficiency and even performance. The only area where the new kid on the block looses out is with the number of cores but in general, its paper specifications do make for some impressive reading. This will be great news to those of you who didn’t jump on the bandwagon but it also causes us wonder if the GTX 465 is being pushed out of the market already. There is however the small matter of the GTX 465’s edge when it comes to the PolyMorph Engines which could give it a serious edge in some DX11 applications.

GTX-460-18.jpg
GTX-460-19.jpg

One of the most interesting aspects of the GTX 460 is that it doesn’t actually sport a full GF104 core. Much like the GTX 480, NVIDIA decided to disable a single SM in order to improve yields and (in a roundabout way) ensure this sub-$250 card wouldn’t end up taking a bite out of the whole 400-series lineup. Will we see a 384-core totting, GF104-based card in the future? You never know but NVIDIA is likely keeping this as an ace up their sleeves in case ATI is able to mount a counter-offensive.

HD5450-21.jpg

Unlike the GF100 cards, the GTX 460 also supports full bitstreaming of HD audio over HDMI. All of the signal processing is done on the card itself without the need for external decoding. This is a huge step forward for those of you who want to use this card in an HTPC environment for decoding Dolby DTS-HD Master Audio and TrueHD tracks.

EVGA’s Warranty, Step-Up and More

EVGA’s Warranty, Step-Up and More


Many of us know EVGA by name since their cards are usually some of the best priced on the market. Other than that, there are several things which EVGA has done to try to differentiate their business model from that of their competition. Not only do they have an excellent support forum and an open, friendly staff but it also seems like they have a love for their products you just can’t find many other places. Passion for one’s products goes a long way in this industry but without a good backbone of customer support, it would all be for nothing. Let’s take a look at what EVGA has to offer the customer AFTER they buy the product.


Lifetime Warranty

GTX280-92.jpg

Every consumer wants piece of mind when it comes to buying a new computer component especially when that component costs you a pretty penny. In order to protect your investment, EVGA offers their customers a lifetime warranty program which is in effect from the day you register the card until…well…the end of time. The only caveat is that you must register your card within 30 days of purchase. Even if you forget to register your card within the 30 days necessary to receive the lifetime warranty, EVGA still offers you a 1 year warranty. So as long as you don’t get lazy or forget, consider yourself covered even if you remove the heatsink. The only thing that this warranty doesn’t cover is physical damage done to your card.

Other EVGA products carry different warranty lengths so we advise you to b vigilant as similar products could carry different warranties.

For more information about the EVGAwarranty you can go here: EVGA | Product Warranty



Step-Up Program

EVGA-GTX465-13.jpg

While some competitors like BFG used to offer trade-up programs as well, EVGA will always be known for having the first of this type of program. This allows a customer with an EVGA card to “step up” their card to a different model within 90 days of purchase. Naturally, the difference in price between the value of your old card and that of the new card will have to be paid but other than that, it is a pretty simple process which gives EVGA’s customers access to newer cards. As is usual certain conditions apply such as the cards being in stock with EVGA and the necessity to register your card but other than that it is pretty straightforward. Check out all the details here: EVGA | Step-Up Program


24 / 7 Tech Support

GTX280-89.jpg

Don’t you hate it when things go ass-up in the middle of the night without tech support around for the next dozen hours or so? Luckily for you EVGA purchasers, there is a dedicated tech support line which is open 24 hours a day, 7 days a week. As far as we could tell, this isn’t farmed out tech support to the nether regions of Pakistan either since every rep we have spoken to over the last few years has had impeccable English. Well, we say that but maybe EVGA hunted down the last dozen or so expats living in Karachi.

A Closer Look at the EVGA GTX 460 768MB Superclocked

A Closer Look at the EVGA GTX 460 768MB Superclocked


EVGA-GTX-460-83.jpg

Unlike past GTX 400-series cards, the GTX 460 has the capability to overclock extremely well without exhibiting horribly high power consumption or extreme temperatures. With their Superclocked card, EVGA includes some surprisingly high clock speeds, especially considering this will be their lowest-end pre overclocked SKU.

Both the memory and engine get significant increases which will actually turn into real-world performance differences between it and the reference card. How much of a difference? We’ll find out in a bit.

EVGA-GTX-460-1.jpg
EVGA-GTX-460-2.jpg

The outside design of EVGA’s boxes has pretty much stayed the same for the past few years with just the right amount of colour splashed onto the black background to make an impression at retail level. However, unlike past products, this one forgoes the plastic clamshell card holder and instead uses a much more environmentally friendly recycled cardboard insert to protect the card.

EVGA-GTX-460-3.jpg

Within this inner sanctum lies the well protected GTX 460 as well as all of the accessories. Included, you get a mini HDMI to HDMI cable, two molex to 6-pin power connectors, a DVI to VGA dongle and some basic documentation. Believe it or not, when it comes to the most recent NVIDIA cards, their software offering is quite extensive with programs like Design Garage and Supersonic Sled being included with every card. EVGA also includes their own overclocking software which we will see a bit later.

EVGA-GTX-460-4.jpg


EVGA-GTX-460-6.jpg
EVGA-GTX-460-7.jpg

EVGA sticks very much to the reference design for their Superclocked Edition with the centrally mounted 72mm intake fan as well as the full-length shroud. At 8 1/4” long it is also one of the shortest cards in the sub-$250 price category but its two 6-pin power connectors do tend to hint at the processing power hidden under its unassuming facade.

Aliens Versus Predator (DX11)

Aliens Versus Predator (DX11)


When benchmarking Aliens Versus Predator, we played through the whole game in order to find a section which represents a “worst case” scenario. We finally decided to include “The Refinery” level which includes a large open space and several visual features that really tax a GPU. For this run-through, we start from within the first tunnel, make our way over the bridge on the right (blowing up several propane tanks in the process), head back over the bridge and finally climb the tower until the first run-in with an Alien. In total, the time spent is about four minutes per run. Framerates are recorded with FRAPS.

DiRT 2 (DX11)

DiRT 2 (DX11)


Being one of the newest games on the market, DiRT 2 cuts an imposing figure in terms of image quality and effects fidelity. We find that to benchmark this game the in-game tool is by far the best option. However, due to small variances from one race to another, three benchmark runs are done instead of the normal two. It should also be mentioned that the demo version of the game was NOT used since after careful testing, the performance of the demo is not representative of the final product. DX11 was forced through the game’s config file. In addition, you will see that these scores do not line up with our older benchmarks at all. This is due to the fact that a patch was recently rolled out for the game which included performance optimizations in addition to new graphics options.

Even though Far Cry 2 has its own built-in benchmarking tool with some flythroughs and “action scenes”, we decided to record our own timedemo consisting of about 5 minutes of game time. It involves everything from run-and-gun fights to fire effects. The built-in benchmarking too was then set up to replay the timedemo and record framerates
